The insight and explanation of the body was great, but then it started to go downhill, this is yet another one of those series that is clearly made simply to push narratives and beliefs (for example evolution). Talking about the body constantly as if evolution and other topics as if it is fact instead of a theory. It’s a real shame when programmes do this, for me Netflix seems to allow this a lot more than most streaming services. I was that sick of hearing them pushing certain things that aren't actually fact that I had to stop watching it, a shame.
